Whoops, I knew that. Wasn't paying close enough attention when I asked
the question; sorry. The other information was indeed helpful, and I
think I basically have it, except:

This is the bit that I'm having problems with--if I #define this at the
top of the file, the line:

nsCOMPtr<cellml_apiICellMLBootstrap> boot(do_GetService(CELLML_BOOTSTRAP_CID,
&rv));

gives me the error:

src/module-cellml.cpp:230: error: expected primary-expression before '{' token
